Specification of Letters Patent.

Patented May 6, 1919.

Application filed January 25, 1916. Serial No. 74,118.

new and useful Couch-Bed, of which the following is a specification.

My. invention relates to combination beds and couches.

An object of the invention is to provide a couch structure of verycompact form which is adapted to be unfolded into a bed of standardsize.

Another object of the invention is to provide a structure of the classdescribed which includes a deep coil spring mattress for the topmattress to rest upon.

Another object of the invention is to provide a couch bed of the classdescribed in which the mattress for the bed serves also as theyieldingseat of the couch when the structure is folded.

The invention possesses other features of advantage which, with theforegoing will be set forth in the following description of thepreferred form of my invention which is illustrated in the drawingsaccompanying and forming part of the specifications. It is to beunderstood that I do not limit myself to the showing made by the saiddrawings and description, as I may adapt variations of the preferredform within the scope of my invention as set forth in the claim.

Referring to the drawings:

Figure 1 is an end elevation of the couch bed of my invention whenfolded'together into compact form. x i

Fig. 2 is an end elevation of the couch bed showing the structure partlyunfolded.

Fig. 3 is an end elevation of the couch bed fully unfolded to provide afull sizebed.

Fig. i is a-fragmentary left side elevation.

Fig. 5 is a fragmentary right side elevation.

Fig.6 is a detail view showing the folding leg of the structure.

Fig. 7 is another detail of the leg showing it in its folded position.

My invention comprises a couch frame upon each of the sides of which ispivoted a mattress supporting frame. The pivotal sup-. ports of thesemattress frames are so arranged on the couch frame and with relation toeach other that the two frames are sup ported within the couch frame,one above the other; when thestructure is folded into its most compactform as shown in Fig. 1; but when it is desired to unfold the structureto provide a bed, the upper frame is temporarily displaced about itspivots to permit the lower frame to be transposed outwardly from thecouch frame and inverted, the upper frame then being dropped back to itsoriginal position and forming with the lower frame'a continuoussupporting frame for the mattresses. The top of the lower frame and thebottom of the upper frame may be formed so that they constitute a seatand back for the structure when the parts are in the position shown inFig. 2. A coiled spring mattress of ample depth is disposed upon eachframe and a top mattress is arranged upon the coil spring mattress. Whenthe lowerframe is transposed and inverted into its unfolded position,the structure provides a bed of full size as shown in Fig. 3 with topmattress and coiled spring mattress of the usual depth and comfort.

i The two ends of the couch frame are alike, and each is formed of themember 2 stiffened near the bottom by the and rail 3 rigidly fastenedthereto. The two ends of the couch frame are secured together by theside rails 4c and 5. Two mattress supporting frames 6 and 7 are providedof such size that they are adapted to lie one above the other within thespace defined by the couch frame. Frame 6 is pivotally mounted upon thecouch frame by means of a heavy fitting or fixture 8 which is bolted toeach end of the frame adjacent one of its sides and which is pivoteduponthe member 2 at the point 9. The fitting 8 is provided with an arm 12which-extends downwardly below theframe 6 when the'latter is in itsfolded position' A long coiled spring 13 coiiiiects the end of thearm-12 to the member 2 on the'opposite side of the couch frame and thisspring is put under tension as the frame 6 is turned to its foldedposition as shown in Fig. 2 and to its transposed or extended positionshown in Fig. 3, thus acting as a counterbalance to the weight of theframe in both positions so that only a minimum of effort is needed tomove the frame from one position to the other. A series of coiledsprings 14: are arranged upon the frame 6 to form a spring mattress inthe well known manner, the springs being disposed upon the under side ofthe frame when in the folded position, so that when the frame is turnedabout its pivots to its transposed inverted position, the springmattress is above the frame.

A leg 16 is pivoted at 17 on the outer side of the frame 6 near eachend. In both the extended position of the leg shown in Fig. 6 and thefolded position shown in Fig. 7, a stop pin 18 positions the leg withrespect to the frame.

From the above, it is seen that the mat tress supporting frame 6together with its coiled spring mattress 14 is pivotally mounted uponthe couch frame ends and may be swung tofolded position within the couchframe or transposed to an inverted osition without the couch frame, theweig t of the frame at the beginning and ending of the movement to bothpositions being counterbalanced by the coil springs 13.

The mattress supporting frame 7 is noni-nvertible, but is of similarstructure to frame 6 and is also provided with a coiled spring mattress.The springs19 comprising this mattress are arranged on the top surfaceof the frame so that they also provide a spring mattress for the seat oryielding surface of the structure'when it is used as a couch. The frame7 is provided at each end with a fitting 21 bolted to the frame andpivoted to the lower end rail 3 at 22. The shape and proportions of thefitting 21, its position on the frame '7 and the position of the pivoton the end rail, are such as to permit the frame 7 to be supported aboveand closely adjacent to frame 6 when all are folded together within thecouchframe and to permit it to be turned upwardly and outwardly aboutits pivots to a vertical position without the couch frame, at whichpoint it clears all the rest of the structure and leaves an unobstructedpath for the unfolding or transposing and inverting movement of thelower frame 6. On the inside of the fitting 8 and axially alined withthe pivot 9 is arranged a boss 24, Fig. 4, upon which the edge of theframe 7 rests in its lowered position. Since the boss is alined with thepivot/9, it is in position to support the free end of the frame 7whether frame 6,is within or without the couch frame. An extension 25 ofthe fitting 21 is connected by a coil spring 26 to a point on the couchframe remote from the pivot 22 andthis spring is placed under tensionwhen the frame 7 is lowered from its vertical position shown in Fig. '2,thus counter-balancing the weight of the frame and rendering it easy toraise and lower. A fitting 27 reinforces the attachment of the side rail5 to the member 2 and is provided with a stop 28 against hich the[itting 21 abuts when the frame 7 is raised to the vertical position.The fitting 27 also carries an upstanding lug 29 upon which the free endof the frame 6 rests when it is folded within the couch frame.

Relative to the couch frame the frame 7 occupies the same position inthe couch form of the structure as it does in thebed form, its swingingmovement to a vertical position and back being merely to permit thelower frame to be moved about its pivots.

A top mattress in two parts 31 and 32 is provided and these parts arepreferably secured one upon the other to the spring mattress 19. Themattresses 31 and 82 are fastened together along the edge 33 and theedges of the lower mattress 31 are secured to the wire edge of thespring mattress 19 by tapes 3% so that the mattress 31 is retained uponthe spring mattress 19 when the latter is raised to the verticalposition.

In the couch form of th structure as shown in Fig. 1, the two topmattresses 31 and 32 are superposed upon the spring mattress 19 and formthe seat or yielding surface of the couch and the whole may be coveredby a suitable spread or drapery. 'VVhen the couch is to be convertedinto a bed, the upper bed section which includes the frame 7 is raisedto the vertical position and the lower bed section which includes theframe 6 transposed outwardly to its invert-ed position. The upper bedsection is then turned down to its original position and the topmattress 32 turned back upon the wire mattress 14:, thus providing afull size bed with top mattress and wire mattress of sufficient depth togive the maximum of softness and resiliency.

I claim:

A couch bed comprising a couch frame, an invertible lower bed sectionpivoted to said couch frame, a non-invertible upper bed section providedwith rigid extension arms, said arms being pivoted intermediate theirends to said couch frame below the plane of the pivots of saidinvertible bed section, and springs connecting the free ends of saidarms, to said couch frame.

In testimony whereof, I have hereunto set my hand at San Francisco,California, this 19th day of January, 1916.
